Some Thoughts on Computers

  1. Physical Abstractions

    The desktop is an abstraction of your physical desktop. The file system abstracts your file cabinet. The mouse button sometimes looks like a hand because it is supposed to represent your physical hand grabbing an object.

    The internet is just one large computer. It’s a big computer made up of lots of smaller computers. Google and other search engines search through the Internet file system. Web addresses are like file paths on your local computer; they represent the sequence of nested file folders you have to open to get to your desired document. Your web browser is like your secretary, keeping track of where you’ve been and how you got there. The web browser also formats files as nicely as it can. Formatting can be hard, because sometimes files are in strange formats. When the Internet is slow, think about how some people are slow to deliver on promises or respond to your messages. This just means that subcomputer is underpowered. More people want to talk to it than it can talk to at one time.

    The internet is like an amusement park. You have to pay an entrance fee to an Internet Service Provider to get in. Once you’re in, they will watch and record everything that you do. This amusement park never closes and pretty much has no rules, so you have to be careful to protect yourself. The EFF is an organization that wants to help protect you. You can download some of their protective tools from the link I attached.

    There is more to the internet and computers, like online advertising and hardware, but those leak beyond the physical abstractions. Feel free to use the internet to learn more about those things.

  2. Copy-Paste-Cut

    This is a computer only tool that is just brilliant. You want to move a whole paragraph of text you just wrote on your word processor? Swoosh, into your register it goes. You like what you just wrote? Well, congratulations, now you have a mini-propaganda horn! Go ahead and paste those few pieces of text everywhere with the simple keyboard shortcut

    -V (or Cmd-V). Unfortunately, most of us live with only one copy register. But you can certainly upgrade on [Mac](https://www.alfredapp.com) and ~sort of~ on [Windows](https://zapier.com/blog/best-clipboard-managers/) to get more registers. Who wouldn't want more propaganda horns? Toot! Toot!
